PPP's newest Florida poll, conducted completely after the Republican convention, finds no change in the Presidential race there. Barack Obama leads Mitt Romney 48-47, exactly as he did on our last poll of the state five weeks ago.

The Republican convention being held in Tampa appears to have been a wash. 33% of voters say it made them more likely to vote for Republicans, 33% said it made them less likely to vote for Republicans, and 34% said it didn't make a difference to them either way.

Romney did see a slight bump in his favorability numbers. 49% of voters have a positive opinion of him to 47% with a negative one. That +2 spread is up a net 5 points from late July when his breakdown was 46/49.

There's also this nugget on the Paul Ryan budget, which doesn't look like an electoral asset for Romney but hasn't dragged him down in the top line numbers yet:

Florida voters oppose the Ryan Plan 44/37 but given the lack of change in the race since Ryan's selection as Romney's running mate and the strong advantage the Republican ticket has with seniors that may not be having too much of an impact.

The caveat here is that it can take time for developments like the convention to sink in. What's more, the fact that the head-to-head numbers haven't changed between Obama and Romney doesn't mean that there haven't been changes in the underlying dynamics of the race. So far, though, the early public data suggests that the Republican convention hasn't transformed the race — and may even raise questions about whether a race this competitive is transform-able in the first place.
